Harper went 2-for-3 with two walks, a double, a run scored and an RBI in Monday's 3-2 extra-inning win over the Astros.
The 31-year-old played hero for the Phillies, walking it off with a 10th-inning single that brought home Kyle Schwarber as the phantom runner. Harper also has a two-bagger in four straight contests, and through 22 games in August he's slashing .287/.354/.460 with nine doubles, two homers, nine RBI and 10 runs.
